891-50 Santovac® 5扩散泵油

Santovac® 5 Diffusion Pump Oil

Operates efficiently, economically and safely in diffusion pumps in properly designed systems to produce ultra-high vacuums in the 10-10 torr range. A wide liquid range, low vapor pressure and balance of properties make it an ideal working fluid in diffusion pumps.
Extremely low vapor pressure results in low ultimate pressures. The vapor pressure of Santovac® 5 at 25°C is 4 x 10-10 as determined by extrapolation from higher temperature data. Together with low backstreaming characteristics, 10-10 torr vacuums can be obtained in well designed systems without the use of nitrogen traps.

Low backstreaming. Santovac® 5 pump fluid can be used for electronic component manufacture, laboratory, analytical, instrument and research applications.
Santovac® 5 offers unusually high thermal and oxidation stability, with isoteniscope tests showing thermal stability at 465°C （870°F）. May discolor with use but this does not affect its operation. Oxidation and corrosion tests, and field experience have shown that Santovac® 5 has little tendency to increase in viscosity during use. Shelf life, in amber glass bottle at ambient temperatures, is up to 40 years

Santovac®5扩散泵油

在设计合理的系统中，在扩散泵中高效，经济，安全地运行，以产生10-10托范围内的超高真空。宽液体范围，低蒸汽压和平衡性能使其成为扩散泵的理想工作流体。
极低的蒸汽压导*低的压力。通过从较高温度数据外推测定，Santovac 5在25℃下的蒸气压为4×10-10。再加上低回流特性，在精心设计的系统中可以获得10-10托的真空吸尘器，而无需使用氮气捕集器。

低回流。 Santovac®5泵流体可用于电子元件制造，实验室，分析，仪器和研究应用。
Santovac®5具有非常高的热稳定性和氧化稳定性，同位素测试显示在465°C（870°F）时的热稳定性。可能会随着使用而变色，但这不会影响其操作。氧化和腐蚀试验以及现场经验表明，Santovac®5在使用过程中几乎没有粘度增加的趋势。在环境温度下，在琥珀色玻璃瓶中的保质期长达40年
